ALBERT C. WEBER, OF INDIANAPOLIS, INDIANA.

SYRINGE.

Application filed January 11, 1923. Serial No. 612,079.

T all whom it may concern:

Be it known that I, ALBERT C. 15mm, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Syringes, of whichthe following is a specification.

My said invention relates to a combined syringe and douche and has forits objects to provide a simple and convenient device of this characterwhich can easily be taken apart and cleaned and to provide for airpressure on the water in the container, while preventing air fromentering the parts in advance of water.

Referring to the accompanying drawing which is made a part hereof and onwhich similar reference characters indicate similar parts,

The single figure is a vertical section of the device.

In the drawings reference character 10 indicates the body of a.container for liquids this being of any convenient size and shape andbeing made of glass or other non-corrodible materials. The container isprovided with a cap 11 adapted to be held firmly in place by a clamp 12engaging ears 18 on the body of the container. A screw 14 serves totighten the cap on the body, the screw engaging the top of the cap andhaving threaded engagement with the clamp. A packing ring of rubber orthe like may be interposed between the body 10 and the cap 11.

At the lower end of the body is a skirt 15 and a bent outlet tube 16passes through a hole in the skirt and through a central opening in thebottom 17 of the container. Flanges 18 and 19 on the tube assist inholding the same in place. A wingnut 2O inside the body 10 draws theflange 19 closely up against the bottom and a washer or washers may beadded to insure against leakage. The pipe 16 terminates in anenlargement 21 and is provided with a plug 22 to regulate or cut. offthe flow of water.

An air pump 2-3 is supported alongside the container by means of a pairof clamping devices consisting of narrow bands con nected so as to formbights 24, 25 and 26 embracing respectively the body 10, a pipe 27leading from the pump to the body, and

the pump body. The pipe 27 is connected in any desirable manner to thebottom of the pump body and the upper end of the container body. Ahandle 28 serves to operate the piston of the pump.

It will be seen that the container 10 may be filled with water on otherliquid up to any desired level and that the pipe 16 and any attachedpipe or tubing may be filled before pumping air into the compressed airspace above the liquid thus preventing the formation of a body ofcompressed air in the pipe 16 or attached tube which must be expelled inadvance of the liquid contents of the container.

It will also be evident that my device may be modified in various waysWithout departing from the spirit of my invention the true scope ofwhich is indicated in the appended claims.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent, is:

l. A device of the character described comprising a closed container forliquids, an air pump alongside the same, a pipe connecting the lower endof the pump to the upper end of the container and one or more clampseach embracing the pump, the pipe and the container, and having meansfor holding the pump, the pipe and the container in spaced relation,substantially as set forth.

2. A syringe comprising a non-metallic receptacle having pairs ofannular flanges at intervals, a pump parallel to the receptacle, a pipeconnecting the receptacle and pump and having a part parallel thereto,and bands located between each pair of annular flanges and closelyembracing the pump, the receptacle and pipe, each of said bands havingfastening devices between the pump, receptacle and pipe for holding themin spaced parallel relation, substantially as set torth.v

In witness whereof. I have hereunto set my hand and seal atIndianapolis. Indiana, this 9th day of January, A. D. nineteen hundredand twenty-three.
